类金刚石碳（DLC）薄膜在生物医学应用中具有重要意义，可改善人造心脏隔膜的组织相容性、血液相容性和耐用性。为了在人造心脏中使用的半球形聚合物隔膜上实现DLC薄膜的均匀沉积，以防止驱动液（硅油）和血液的相互扩散，使用改进的电极通过化学气相沉积进行涂层。在隔膜驱动操作之前和之后，通过红外光谱和电子光谱进行化学分析，研究了所生产的薄膜的化学和物理性能及其耐久性。将薄膜的均匀性与传统电极获得的DLC薄膜进行比较，结果表明薄膜的均匀性可以得到改善，从而获得生物医学应用所需的具有良好耐久性和优异粘附性能的DLC薄膜。
Diamond-like carbon (DLC) films are interesting in biomedical application for the improvement of the histocompatibility, blood compatibility and durability of diaphragms in artificial hearts. In order to achieve uniform deposition of DLC films on hemispherical polymer diaphragms used in artificial hearts to prevent inter-diffusion of driving fluid (silicone oil) and blood, coating has been performed by chemical vapor deposition using improved electrodes. The chemical and physical properties of the produced films as well as their durability have been investigated with infrared spectroscopy and electron spectroscopy for chemical analysis before and after the driving operation of the diaphragm. The uniformity of the films has been compared with DLC films obtained with conventional electrodes showing that the uniformity could be improved, thus obtaining DLC films with good durability and excellent adhesion properties as required for biomedical application.
